The critical electric fields of hot SF6 are calculated including both electron and ion kinetics in wide ranges of temperature and pressure, namely from 300 K up to 4000 K and 2 atmospheres up to 32 atmospheres respectively. Based on solving a multi-term electron Boltz- mann equation the calculations use improved electron-gas collision cross sections for twelve SF6 dissociation products with a particular emphasis on the electron-vibrating molecule interactions. The ion kinetics is also considered and its role on the critical field becomes non negligible as the temperature is above 2000 K. These critical fields are then used in hydrodynamics simulations which correctly predict the circuit breaker behaviours observed in the case of breaking tests.

The main current benefit of collaboration between Quaternary scientists and palaeoanthropologists (especially palaeolithic archaeologists) lies in providing a unique perspective on how human populations respond to long-term climate change. Eurasia has a superlative record of climatic changes over the last two million years, and an archaeological record that is regionally variable in quality, but which is drawn from a wide range of environmental and chronological contexts. At a continental scale, the integration of these records allows the past 2 Ma to be divided into six major themes of how hominins (our remote ancestors) and our own species responded to climatic changes at Milankovitch and sub-Milankovitch scales. These themes are the initial hominin colonisation of Asia after ∼2 Ma; the dispersal of hominins into Europe in the Early Pleistocene and its eventual permanent colonisation in the Middle Pleistocene; the expansion of Acheulean, bifacial assemblages from the Levant to western Europe and India after 600 ka; the responses of hominin populations to Milankovitch-length climatic changes during the Middle Pleistocene; the expansion of modern humans after 100 ka across Eurasia and later into Australasia and the Americas; and the recolonisation at millennial scales of abandoned areas of Eurasia at the end of last ice age. As the quality of Quaternary and archaeological information improves, these responses of past human populations to climatic change will be documented at a level of detail unimaginable a few decades ago. Cumulatively, this type of collaboration provides a unique perspective on the consequences of large-scale climatic change upon human populations that is particularly relevant to current concerns of climate change.

Alteration in skin microbiome profile is involved in many skin conditions, therefore, microbiome modulation is a reasonable target for skin health. Probiotic skincare was suggested, and leave-on synbiotic skincare preparation, blending bacillus spores, as probiotic active ingredient, and inulin sugar, as prebiotic booster, is evaluated, using microarray, 16S gene sequencing, and clinical skin analyses. Topical application of leave-on synbiotic skincare on skin model activates a profound effect on skin biology, expressed in the transcriptome level, with higher than 10% affected genes. The significance of the synbiotic preparation on skin biology was assured, indicating the involvement of major biological pathways. Blending probiotic with Polygonum aviculare plant extract, had triggered a distinct gene expression alteration, demonstrating the sensitivity of skin responses to different active substances. A synbiotic skincare application, had successfully introduced live and active Bacillus probiotics on human skin, detectable days after application was finalized. Following synbiotic application, the microbial content of several microorganisms, related to skin pathologies, was reduced, while the content of bacillus species, representing a healthier microbiome status, was increased, suggesting that frequent application may lead to overall healthier skin microbiome. Acne vulgaris involves unbalanced skin microbiome, with expansion of Cutibacterium acnes. The efficacy of a synbiotic skin cream was assessed to improve acne symptoms, including IGA dermatologist acne severity score, the number of counted acne lesions, measured skin oiliness and skin redness, visual appearance of skin-pores, skin smoothness and softness, and Acne Quality of Life Index.
